NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 223,622, dated January13, 1880.

application filed August 30, 1879.

To all whom it may concern Be it known that I, J OSEPH PATTEN WIL- SON,of Minneapolis, in the county ofHennepin and State of Minnesota, haveinvented certain new and useful Improvements in Nut-Locks, of which thefollowing is a specification.

The object I have in view is to produce a lock for the nuts on thefish-bolts of railroadrails which will be simple and inexpensive inconstruction, can be easily and quickly applied, and will securely holdthe nuts from turning, the construction and manner of applying thelockin g device being such that it can be stam ped complete from verylight sheet metal, and will be strong and secure.

My invention therein consists in a plate for holding a single nut,having a hole punched through it, so that it can be set over the end ofthe bolt between the nut and the fish-plates, and having its lower edgeturned outwardly to give a broad bearing upon the rail-flange,

and provided with radial tongues, situated at the sides of the plate ontop of such plate and at intermediate points, so that by bending outsuch tongues the nut can be held when its sides are parallel andperpendicular with the tread of the rail, or when they are oblique tothe plane of the tread, such tongues being separated by angular orV-shaped slots, so that they can be readily bent and the plate can bestamped out complete, all as fully hereinafter explained. a

In the accompanying drawings, forming a part hereof, Figure l is a sideelevation of a portion of a rail and fish-plates, showing a single nutheld by my improved locking device Fig. 2, a cross-section of the sameparts,

and Fig. 3 a separate view in perspective of the locking-plate.

Like letters denote corresponding parts.

A is the locking'plate, stamped at one operation from thin sheet metal.It is of nearly semicircular form in outline, and has a straightstronger than if such edge were cut away at 5 the center to form sidelegs. This edge a is turned outwardly to fit and rest upon the beveledupper surface of the flanged base of the rail. Above the foot of thelocking-plate it is cut away on each side, and above these cutawayportions is provided with side tongues, b, a top tongue, 0, andintermediate tongues, d. All these tongues project from the plate onlines radial to the center of the bolt-hole e, which is punched throughthe center of the plate, thetongues b projecting horizontally, thetongues c vertically, and the .tongues d at an angle of about forty-fivedegrees,

The tongues b c d have parallel sides and are separated by angular orV-shaped slots or. cut-away portions f, so that such tongues can.

be easily bent up without interfering with each other, and the plate canbe stamped out complete, which is not the case where the divisionsbetween such tongues are slits, which have to be out with shears.

The use of the improved locking-plate is ap parent from the drawings.

When the nut is in the position shown one or more of the tongues b 0 canbe bent out against its sides. When turned half waythat is, with acorner. upward-one or both of the tongues 41 can be used.

What I claim as my invention is The plate A, for looking single nuts,having straight out-turned lower edge, a, bolt-hole c, and horizontal,vertical, and oblique radial tongues b c d, separated by angular slots,substantially as described and shown.

This specification signed and witnessed this 14th day of July, l879.
